Hey just took out the turbo balt, after i go over 3000rpm i get the p0068 MAP/MAF correlation code......whats this from?? I cant even get into the throttle without going into reduced power mode. Help me out, im going go go work on the car a bit more hopefully someone will have the answer for me when i get back.

 

Sounds like a bad MAF sensor, I had same problem with mine, Tried cleaning but didnt do anything. I would start there.

 

go into the diagnostics in hptuners and set the enable rpm for p0068 to 8000 rpms. problem solved

 

That sounds good Bika, Gotta Love HP

 

yup hpt FTW
for the 2007 ss/sc GM actually set p0068 to 8000 rpm. they hadn't yet figured that one out in '05 and '06

 

I have this same code with my turbo. How safe is it to do that?

 

u have no choice

 

you can either. live with it in limp mode. or shut it off.

turbo vs blower.

my advice, shut it off.

 

Shut it off, no way around it. Mine's been shut off since I went turbo.

 

Im having this problem too with my supercharged cobalt... I keep taking it to the nearest GM dealer and they said they cant figure out whats wrong with... They replaced my MAP sensor but my check engine light still keeps coming on...

 

replace the mas air sensor.

 

ok my MAF and MAP sensors have both been replaced but i still have a MAF/MAP correlation code on. Any ideas why?

 

what exactly is the DTC number, and what mods does the car have?

 

I had my car in the shop for almost about a month and GM couldnt figure out my problem.. They replaced both my MAP/MAF sensors and I still had my code coming on. I just happen to put on a cold air system and it fixed everything. My stock air box had a huge hole in it which i think was causing that code to come on.
